AB  - The  hip  joint,  or  coxofemoral  joint,  is  the  articulation  of  the  acetabulum  of  the  pelvis  and  the  head  of  the  femur  (Fig.  10–1).  These  two  segments  form  a  diarthrodial  ball-and-socket  joint  with  three  degrees  of  freedom:  flexion/extension  in  the  sagittal  plane,  abduction/adduction  in  the  frontal  plane,  and  medial/lateral  rotation  in  the  transverse  plane.  Although  the  hip  joint  and  the  shoulder  complex  have  a  number  of  common  features,  the  functional  and  structural  adaptations  of  each  to  its  respective  roles  have  been  so  extensive  that  such  comparisons  are  more  of  general  interest  than  of  functional  relevance.  The  role  of  the  shoulder  complex  is  to  provide  a  stable  base  on  which  a  wide  range  of  mobility  for  the  hand  can  be  superimposed.  Shoulder  complex  structure  gives  precedence  to  open-chain  function.  The  primary  function  of  the  hip  joint  is  to  support  the  weight  of  the  head,  arms,  and  trunk  (HAT)  both  in  static  erect  posture  and  in  dynamic  postures  such  as  ambulation,  running,  and  stair  climbing.  The  hip  joint,  like  the  other  joints  of  the  lower  extremity  that  we  will  examine,  is  structured  primarily  to  serve  its  weight-bearing  functions.  Although  we  examine  hip  joint  structure  and  function  as  if  the  joint  were  designed  to  move  the  foot  through  space  in  an  open  chain,  hip  joint  structure  is  more  influenced  by  the  demands  placed  on  the  joint  when  the  limb  is  bearing  weight.  As  we  shall  see  later  in  this  chapter,  weight-bearing  function  of  the  hip  joint  and  its  related  weight-bearing  responses  are  basic  to  understanding  the  hip  joint  and  the  interactions  that  occur  between  the  hip  joint  and  the  other  joints  of  the  spine  and  lower  extremities.
